Ultraviolet absorption in lenses.

Polarizabilities of the nucleon and spin dependent photo-absorption

The polarizabilities α (electric), β (magnetic) and γπ (backward spin) of the nucleon are investigated in terms of the degrees of freedom of the nucleon using recent results for the CGLN amplitudes and resonance couplings A1/2 and A3/2. The photon excitation strengths of the excited states are given in terms of partial integrated photoabsorption cross sections and resonant contributions of the ...

Jovian Atmosphere: Near-Ultraviolet Absorption

Greenspan and Owen (1), in a stimulating discussion of the Jovian atmosphere, have reconsidered Stecher's (2) rocket ultraviolet spectroscopy of Jupiter. They conclude that, while the general reflectivity between 2000 and 3000 A can be matched by some 12 km-atm of H2 and a small surface reflectivity, there still exist two significant absorption features in this wavelength range. This residual a...

Semiclassical spin transport in spin-orbit-coupled bands.

Motivated by recent interest in novel spintronics effects, we develop a semiclassical theory of spin transport that is valid for spin-orbit coupled bands. Aside from the obvious convective term in which the average spin is transported at the wave packet group velocity, the spin current has additional contributions from the wave packet's spin and torque dipole moments. Electric field corrections...

New vacuum-ultraviolet absorption data for lead vapour obtained by spin-polarisation measurements

The photoelectrons emitted by lead atoms exposed to circularly-polarised vuv radiation are partially spin polarised. Unlike the photoionisation cross section, the measured polarisation does not show autoionisation resonances as a function of wavelength. The polarisation and the known cross section results together yield new absorption data, which can be compared with the oscillator strengths of...
